Deep groove ball bearing structure
Deep groove ball bearing structure is simple, compared with other types of easy to achieve high manufacturing accuracy, so it is easy to series mass production, manufacturing costs are also lower, the use of extremely common. In addition to the basic type of deep groove ball bearings, there are various variants of structure, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seal, deep groove ball bearings with stop groove, deep groove ball bearings with large load capacity with ball loading gap, double row deep groove ball bearings.
Deep groove ball bearing types
Deep groove ball bearings are mainly used to carry radial loads, but they are also commonly used to carry combined radial and axial loads. Especially when the speed of mechanical equipment is very high and it is not suitable to use thrust bearing, the bearing can be used to bear two-way pure axial load and no maintenance is needed during the working period, which is a kind of bearing with low price and wide application. Deep groove ball bearing models are: deep groove ball bearings (60000 type); deep groove ball bearings with outer ring stop groove (60000N type); deep groove ball bearings with dust cover on one side and stop groove on the other side (60000-ZN type); deep groove ball bearings with dust cover on both sides and stop groove on the outer ring (60000-2ZN type); deep groove ball bearings with dust cover on one side (60000Z type); deep groove ball bearings with dust cover on both sides. type); deep groove ball bearing with dust cover on both sides (60000-2Z type); deep groove ball bearing with seal on one side (60000-LS type, 60000-RZ type); deep groove ball bearing with seal on both sides (60000-2LS type, 60000-2RZ type); deep groove ball bearing with flange outer ring (F60000 type); deep groove ball bearing with flange outer ring with dust cover on one side Ball bearing (F60000-Z type); two sides with dust cover flange outer ring deep groove ball bearing (F60000-2Z type) a total of 11 kinds.
According to the size of deep groove ball bearings can be divided into.
(1) Miniature bearings ---- nominal outer diameter size range of 26mm or less bearings;
(2) Small bearings ---- with a nominal outside diameter of 28-55mm;
(3) Small and medium-sized bearings ---- with a nominal outer diameter size range of 60-115mm;
(4) Medium and large size bearings ---- with a nominal outer diameter size range of 120-190mm
(5) Large size bearings ---- with a nominal outer diameter size range of 200-430mm;
(6) Extra-large bearings ---- with a nominal outside diameter of 440mm or more.
Deep groove ball bearing processing form
The processing forms of deep groove ball-bearing parts are as follows.
1, multi-process processing: general bearing production requires 20 to 40 processes, as many as 70 more.
2, molding processing: bearing parts are rotary molding surface, suitable for processing with molding method.
3, precision machining: the majority of the surface of the bearing parts to be ground, grinding size and geometric accuracy are in μm units.
